tubs'or tanks used for containing vinegar or other acids; and the object of the invention is to provide means by which the soakage of the acids through the staves shall be prevented fromacting upon and destroying the metal hoops employed in binding the said staves together.

It consists, essentially, of a series of strips or projections arranged longitudinally around the outside of the tub or tank to receive the binding-hoops and hold them away from contact with the outer surface of the staves which become soaked with the vinegar or other acid zvliich may be contained within the tank or The drawing represents a perspective view of my improved tub or tank.

In my experience as a manufacturer of vinegar I have, in common withother vinegarmanufacturers, sufi'ered a good deal of annoyanceand loss by the rusting and breaking of the binding-hoops which surround the vinegar tubs or tanks, andwhich are destroyed staves. To preventthis destruction I arrange around the tub or tank A a series of strips B, and paint the inner surface of each strip with a heavy coating of any-suitable liquid-proof paint. Around thesestrips the hoops C fit. It will be observed that the strips B are longitudinally placed around the tub or tank A, so

that the hoops 0 maybe driven into position in exactly the same manner as though they Were immediatelyin contact with the surface ofthc staves, and as a matter of fact they are much easier driven into position, as the staves space between the strips 13 enables the hoops to be driven into position without the mallet comuid-proof paint the acid which soaks through the staves cannot reach the iron hoops, and as a consequence the hoops will remain in perfect condition for years, whereas without the strips the acid soaking through the staves very soon eats into and destroys the metal hoops.

What I claim as my invention is 1. The combination, with a receptacle A, formed with a plurality of Wooden staves, of a'plurality of strips B, resting against said staves and extending lengthwise thereof, and the hoops around said strips, substantially as and for the purpose specified.
